Changes between 1.0.2r and 1.0.2s [xx XXX xxxx]
*) Change the default RSA, DSA and DH size to 2048 bit instead of 1024.
This changes the size when using the genpkey app when no size is given. It
fixes an omission in earlier changes that changed all RSA, DSA and DH
generation apps to use 2048 bits by default.
[Kurt Roeckx]
*) Add FIPS support for Android Arm 64-bit
Support for Android Arm 64-bit was added to the OpenSSL FIPS Object Module in
